Patent number: 8439521Abstract: According to one embodiment, a light-emitting module includes a substrate, a light-emitting element, a light distribution control member, and a cover. The substrate includes a surface on which a thermally conductive portion and a interconnect pattern are formed. The light-emitting element is thermally connected to the thermally conductive portion, is electrically connected to the interconnect pattern, and generates heat while emitting light. The light distribution control member is thermally connected to the thermally conductive portion at a periphery of the light-emitting element, includes a ridge portion formed on an exit side where light emitted from the light-emitting element is projected, and is configured to control distribution of the light emitted from the light-emitting element. The cover is thermally connected to the ridge portion and configured to pass therethrough the light emitted from the light-emitting element.Type: GrantFiled: September 15, 2011Date of Patent: May 14, 2013Assignees: Toshiba Lighting & Technology Corporation, Kabushiki Kaisha ToshibaInventors: Keiichi Shimizu, Hiroaki Watanabe, Naoki Sugishita, Homare Takai

Patent number: 8393765Abstract: A luminaire includes a light-emitting unit, a main body frame, a support frame, and a lighting unit. The light-emitting unit mounts light-emitting elements. The main body frame supports the light-emitting unit, and is formed rectangular having a hook-shaped engaging piece on one side. The support frame is formed rectangular surrounding the outer periphery of the main body frame, and has a groove-shaped receiving place to engage with the engaging piece of the main body frame, on one internal side. The lighting unit turns on the light-emitting elements.Type: GrantFiled: December 3, 2009Date of Patent: March 12, 2013Assignees: Toshiba Lighting & Technology Corporation, Kabushiki Kaisha ToshibaInventors: Naoki Sugishita, Homare Takai, Takafumi Oishi, Yasuhiko Ishii, Masanao Hieda, Yutaka Hashimoto
